Phalaenopsis cultivation greenhouse heating and humidification soil source heat pump system

Abstract

The invention discloses a soil-source heat pump system for heating and humidifying phalaenopsis planting greenhouse. The soil-source heat pump system comprises a burying pipe, a heating circulation assembly, a cooling and humidifying circulation assembly and a refrigerant circulation assembly, wherein the heating circulation assembly and the cooling and humidifying circulation assembly are communicated with the burying pipe; and the refrigerant circulation assembly exchanges heat with the heating circulation assembly and the cooling and humidifying circulation assembly. The soil-source heat pump system disclosed by the invention has the advantages that the operation is reliable and stable in winter, and fuel such as coal is not needed for driving; for the system with good operation in heating in winter, the operating cost can be saved by 30-40%, and high efficiency and economical efficiency of the system are guaranteed; a great amount of land sources are saved, and pollutants such as CO2 and SO2 discharged by coal burning are reduced.

Description

technical field [0001] The invention relates to the technical field of air conditioning and refrigeration, in particular to a soil source heat pump system for heating and humidifying a Phalaenopsis cultivation greenhouse. Background technique [0002] At present, energy shortage has become a key issue that seriously restricts my country's economic and social development, and energy conservation is an important part of the national energy strategy. In the process of cultivating some precious flowers such as Phalaenopsis, there are high requirements on temperature and humidity. Generally, the indoor temperature should not be less than 15°C in winter, not more than 28°C in summer, and the annual indoor humidity should not be less than 80%. To meet the requirements, coal-fired boilers and hot air fans are mostly used in the market today for heating, and wet curtains are used for humidification. Using this system consumes a lot of energy, takes up a lot of land resources, and it ...

AI Technical Summary

Problems solved by technology

[0007] The problem to be solved by the present invention is to provide a soil source heat pump system for warming and humidifying greenhouses for Phalaenopsis cultivation, which solves the problems that the existing coal-fired boilers for greenhouse heating occupy a large area, cause great environmental pollution, and have low energy utilization; The heat dissipation problem of the hot air fan is uneven; and it solves the shortcomings of the air source heat pump such as difficult defrosting and unstable operation, and solves the shortcomings of the water source heat pump such as strong geographical restrictions and restrictions on the geological structure of the water layer
